Abstract

A method of organizing and rescuing simultaneously failing connections in a communications system using a multiple-access forward rescue-channel configuration using a common long-code mask and a reserved or common orthogonal channel code. Signalling on th multiple-access forward rescue channel bears MS-addressed rescue handoff messaging. The multiple-access forward rescue channel is transmitted by one or more sectors in the network for use in soft handoffs as well as rescue (14,16). A failing MS (10) may attempt to receive a message addressed to the failing MS on the multiple-access forward rescue channel and have its connection rescued using the message information.
